Pseudohydnum gelatinosum, commonly known as the toothed jelly fungus, cat's tongue, or jelly tooth, is a species of fungus in the order Auriculariales. Its common names refer to its gelatinous consistency and hydnoid (toothed) undersurface. Found in Eurasia, the mushroom is edible.

Coniophora puteana (commonly known as a cellar fungus) is a wet rot (specifically brown rot fungus belonging to the division Basidiomycota. It has the appearance of large brown patches surrounded by white edges typically found in humid areas on pine as well as hardwood. The mycelium of C. puteana is not always present and often leaves a very thin layer of healthy wood making the fungus very difficult to detect before the structure becomes instable. Contrary to most brown rot fungi C. puteana behaves more like a white-rot fungi in the way it decays, such as the thinning of the cell walls and

Heterodermia is a genus of foliose lichens in the family Physciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 70 species. Heterodermia was historically confused with the related genus Anaptychia, but was distinguished in 1965 based on differences in spore structure and chemical composition. These lichens can be identified in the field using simple chemical spot tests that produce distinctive colour changes when applied to the thallus. The lichens in this genus are small- to medium-sized, usually pale grey in colour, comprising narrow lobes

Acarospora bullata, commonly known as cracked lichen, is a species of lichen in the Acarosporaceae family. The British Lichen Society wrote in 2010 that Acarospora bullata, when seen in North America, has been described as conspecific to Acarospora rugulosa. This species is also known to be conspecific with Acarospora subcastenae and Acarospora mendozana.
